Adjustable/Full Speed Mode Selection Input Pin. Output voltage follows 1.6 times of the voltage
on VSET pin. If the FSM is at low level, the IC operates in full speed mode with the P-channel
MOSFET fully turned on. The FSM pin is pulled low by an internal resistor.
Supply Voltage Input Pin. Supply voltage can range from 4.5V to 6V. Bypass with a 1 F (typical)
capacitor to GND
Regulator Output. Sources up to 600mA. A small capacitor is needed and connected from this pin
to ground to assure stability.
Output Voltage-Set Input. The output voltage follows the 1.6 times of the VSET voltage.
Ground. These pins are internally connected with the internal leadframe. Connect these pins to a
wide ground plane for good heat dissipation.
